A unique new study led by Professor Gilles-Eric Seralini has shown that the first genetically-modified GM crop commercialized for animal feed, Bt176 from Novartis (now Syngenta), was toxic to cows over the long-term.

An antibiotic resistance marker gene was used in the genetic transformation, and the plant produced a new modified insecticide like all Bt plants. Yet only one nutritional test was conducted by Novartis on four cows for two weeks; one cow died after a week without scientific explanation. Continue reading »
